Abstract

The paper reviews the experience in the float-over assembly of marine platforms available in Russia and abroad to analyze the aspects of rational transport and installation operations and step-wise procedures. Requirements are formulated for heavy-lift vessels intended to carry the substructure and topsides to the installation site of semi-submersible drilling rigs at sea. Specific features of the mooring systems used during installation are discussed, as well as the design of mating structures providing the substructure and topsides juncture accompanied by the deformation of the substructure.
